    Hi, when i run iso or cso on my psp phat it doesn't work, gives an error saying the game could not be started (80020148). This only happened recently after i updated to 3.90 M33-2 and i have tried formatting memory stick, restoring default settings, used all types of iso mode ... i seriously dont know whats up unless i wasn't supposed to upgrade my psp phat to 3.90 M33-2!
    Please help ...

    Thanks

    moved to mod & firmware forum

    Go into the Recovery Menu>Configuration>UMD Mode. Switch it to Sony NP9660

    Hi, i had the exact same problem. Well annoying however.....

    bigbadp is correct, put in an original (or demo disc as i have done) and start the game then, that will get it working

    forgot to mention, make sure in your recovery console under configuration that you have UMD mode set to 'Normal -UMD Required'
